Machine tool generating linear, axial working stroke - has toggle lever linked to working piston via slide dog displaced in piston parallel to stroke axis

摘要

The working stroke starts at a lower clamping force and ends with a high such force. There is a tool (8) holder (7) to which is coupled a working piston (1), guided in the stroke axis (I) direction in the machine frame (6). A second working piston (4) is incorporated between the first piston and stroke counter-bearing (5) fixed in the frame. The second piston is driven by a toggle lever (2,3) to generate the linear working stroke and to swivel the stroke axis. The toggle lever is linked to the second working piston via a slide dog, moving in the second working piston parallel to the stroke axis. USE/ADVANTAGE - For a machine forming connections between steel sheet components, with the drive piston remaining axially aligned during the entire stroke course.
